What is the difference between formula mass and the molecular mass of a compound?
1 mol is equal to 6.02214179(30)×1023 molecules of the substance. The molecular weight is how much grams these molecules (6.02214179(30)×1023) weigh. Meaning g/mol.
A compound formed of 0.059 mol hydrogenand 0.94 mol oxyegn has a molecular mass of 34.0what is the molecular formula of this compound?
The molar ratio of hydrogen to oxygen in the compound is 1:1. This means the compound is water (H2O), which has a molecular mass of 18.0 g/mol, not 34.0 g/mol. The given molecular mass of 34.0 g/mol does not match the properties of water.
How many molecules of sulfur tetrafluoride are present in 2.13 moles of this compound?
There are 1.28x10^24 molecules of SF4. 2.13 mol * 6.022x10^23 molecules/mol = 1.28x10^24 molecules.
The empirical formula of a compound is CH2O The molar mass of the compound is 180 g What is the molecular formula for this compound?
The empirical formula CH2O has a molar mass of 30 g/mol (12 g/mol for C + 2 g/mol for H + 16 g/mol for O). To find the molecular formula, which is a multiple of the empirical formula, you divide the molar mass given (180 g/mol) by the empirical formula mass (30 g/mol), giving you 6. Therefore, the molecular formula for the compound is (CH2O)6, which simplifies to C6H12O6, the molecular formula for glucose.
A compound formed of 0.059 mol hydrogen and 0.94 mol oxygen has a molecular mass of 34.0 gmole What is the molecular formula of this compound?
The molar ratio of hydrogen to oxygen in the compound is 2:1. To find the empirical formula, divide the moles of each element by the smallest number of moles, which is 0.059 mol for hydrogen. This gives a ratio of 1:0.5 for hydrogen and oxygen, which simplifies to the empirical formula H2O. To find the molecular formula, calculate the molecular mass of H2O (18 g/mol) and divide the given molecular mass (34 g/mol) by the empirical formula mass to get the multiplier of 2. So, the molecular formula of the compound is H2O2.

How many representative particles are in 4.51 g of a molecular compound with a molar mass of 273 grams?
4.51 g x 1 mol x 6.022 x 1023 molecules = 9.95 x 1021 molecules .............273 g ............... 1 mol
What is the molecular weight of a compound in daltons and how does it convert to grams per mole (g/mol)?
The molecular weight of a compound is measured in daltons, which is a unit of mass used for atoms and molecules. To convert daltons to grams per mole (g/mol), you can use the conversion factor 1 dalton 1 g/mol. This means that the molecular weight in daltons is equal to the molecular weight in grams per mole.
What is the molar mass of a compound if its molecular weight is 58.44 dalton g/mol?
The molar mass of a compound is the same as its molecular weight, which is 58.44 g/mol.
How many molecules of sulfur tetrafluoride are present in 2.13 moles of this compound?
There are 1.28x10^24 molecules of SF4. 2.13 mol * 6.022x10^23 molecules/mol = 1.28x10^24 molecules.
How many molecules of CH4 are in 2.52 mol of CH4?
There are 1.52 x 10^24 molecules of CH4 in 2.52 mol of CH4.
The empirical formula of a compound is CH2O The molar mass of the compound is 180 g What is the molecular formula for this compound?

Therefore, the molecular formula for the compound is (CH2O)6, which simplifies to C6H12O6, the molecular formula for glucose.
What is the molecular weight of a compound in daltons converted to grams per mole (g/mol)?
To convert the molecular weight of a compound from daltons to grams per mole (g/mol), you need to divide the molecular weight in daltons by the Avogadro constant (6.022 x 1023). This will give you the molecular weight in grams per mole (g/mol).

So, the molecular formula of the compound is H2O2.
What is molecular mass for aldehyde?
The molecular mass of an aldehyde depends on the specific compound. For example, the molecular mass of formaldehyde (CH2O) is 30.03 g/mol, while the molecular mass of acetaldehyde (C2H4O) is 44.05 g/mol. You can calculate the molecular mass by adding up the atomic masses of all the atoms in the compound.
What is the molecular formula of the compound CH2 with a molar mass 42.0 gmol?
The molecular formula of the compound is C2H4, which has a molar mass of 28 g/mol. Since the given compound has a molar mass of 42.0 g/mol, it must include an additional CH2 group, resulting in the molecular formula C2H6.
